Here is what I know about it:
I think it is so expensive cose the Moonclth,
cose you can create one onley every 4 days..thats the cooldown:(
Purifying Mooncloth requires 250 skill in Tailoring and can be learned from a pattern which can be bought from Qia or Evie Whirlbrew (unlimited supply) in Everlook.
The pattern can also apire as a drop ,
for example : in Winterspring off a wildkin
The procedure requires two Felcloth, must be performed near a Moonwell and can only be performed once every four days.
You need a moonwell to and there is a moonwell in the middle of the park in Stormwind.
You get felcloth from the satyrs south of jaedenar in the ruins of constellas. On average you can get 1 every 30 minutes, so one hour to get 2 felcloth. Then every 4 days you can use any moonwell (there's one conveinently loacted in the Ruins of Constellas too) to make a mooncloth.
Moonwells:
1. In Ashenvale
2. Outside of Dire Maul easy to sneak by guards
3. In Moonglade
4. In silithus, this is the easiest to get to for anyone 58+ u can set up your hearth there
5. In the Park distric inside SW (Alliance only)
6. In the Moon temple in Darnassus, the pool with the Elven Godess is a moonwell. (Alliance only)
